WARPAGE-COMPENSATED BONDED STRUCTURE INCLUDING A SUPPORT CHIP AND A THREE-DIMENSIONAL MEMORY CHIP

A first semiconductor die and a second semiconductor die can be bonded in a manner that enhances alignment of bonding pads. Non-uniform deformation of a first wafer including first semiconductor dies can be compensated for by forming a patterned stress-generating film on a backside of the first wafer. Metallic bump portions can be formed on concave surfaces of metallic bonding pads by a selective metal deposition process to reduce gaps between pairs of bonded metallic bonding pads. Pad-to-pad pitch can be adjusted on a semiconductor die to match the pad-to-pad pitch of another semiconductor die employing a tilt-shift operation in a lithographic exposure tool. A chuck configured to provide non-uniform displacement across a wafer can be employed to hold a wafer in a contoured shape for bonding with another wafer in a matching contoured position. Independently height-controlled pins can be employed to hold a wafer in a non-planar configuration.
